.SH "SYNOPSIS"
.sp
.nf
CREATE TEXT SEARCH DICTIONARY \fIname\fR (
TEMPLATE = \fItemplate\fR
[, \fIoption\fR = \fIvalue\fR [, \&.\&.\&. ]]
)
.fi
.SH "DESCRIPTION"
.PP
\fBCREATE TEXT SEARCH DICTIONARY\fR
creates a new text search dictionary\&. A text search dictionary specifies a way of recognizing interesting or uninteresting words for searching\&. A dictionary depends on a text search template, which specifies the functions that actually perform the work\&. Typically the dictionary provides some options that control the detailed behavior of the template\*(Aqs functions\&.
.PP
If a schema name is given then the text search dictionary is created in the specified schema\&. Otherwise it is created in the current schema\&.
.PP
The user who defines a text search dictionary becomes its owner\&.
.PP
Refer to
Chapter\ \&12
for further information\&.
.SH "PARAMETERS"
.PP
\fIname\fR
.RS 4
The name of the text search dictionary to be created\&. The name can be schema\-qualified\&.
.RE
.PP
\fItemplate\fR
.RS 4
The name of the text search template that will define the basic behavior of this dictionary\&.
.RE
.PP
\fIoption\fR
.RS 4
The name of a template\-specific option to be set for this dictionary\&.
.RE
.PP
\fIvalue\fR
.RS 4
The value to use for a template\-specific option\&. If the value is not a simple identifier or number, it must be quoted (but you can always quote it, if you wish)\&.
.RE
.PP
The options can appear in any order\&.
.SH "EXAMPLES"
.PP
The following example command creates a Snowball\-based dictionary with a nonstandard list of stop words\&.
.sp
.if n \{\
.RS 4
.\}
.nf
CREATE TEXT SEARCH DICTIONARY my_russian (
template = snowball,
language = russian,
stopwords = myrussian
);
.fi
.if n \{\
.RE
.\}
.SH "COMPATIBILITY"
.PP
There is no
\fBCREATE TEXT SEARCH DICTIONARY\fR
statement in the SQL standard\&.
.SH "SEE ALSO"
